With the configfs data, the driver now is able to negotiate the format with the usb host in the kernel and also exports the supported frames/formats/intervals via the v4l2 VIDIOC interface. The uvc userspace stack is also under development. One example is an generic v4l2uvcsink gstreamer elemnt, which is currently under discussion. [1] [1] https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1304 With the libusbgx library [1] used by the gadget-tool [2] it is now also possible to fully describe the configfs layout of the uvc gadget with scheme files.

The goal is to simply start a uvc-gadget with the following commands: $ gt load uvc.scheme $ gst-launch v4l2src ! v4l2uvcsinkv4l developers, given a lack of review response to this series, I'm assuming that you all have no objection to this series and I can take it through my usb-next tree.
Since this will not apply anymore, I just send v8 with some minor changes. Regards, Michael -- Pengutronix e.K. | | Steuerwalder Str. 21 | http://www.pengutronix.de/ | 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 |
